In general, Florida's disdain for law and order can lead to some pretty scary chaos. (Just check out the assault weapon arsenal in the trunk of our Buick.) But sometimes Miami's libertarian tilt is refreshing. With few exceptions, you can pretty much let your dogs roam free in parks around the Magic City, even if it's technically illegal. And there is no greater little slice of dog heaven than Pinetree Park, a Miami Beach haven on Pinetree Drive just north of 44th Street. There are two fenced-in dog runs here, but why put Fido in a ghetto when the entire park is basically Lollapalooza for pooches? Just pick a park bench and let your dog do his thing with the butts and the sniffing and the lifting of the leg. Oh, and Pinetree ain't a bad place for humans either. It overlooks the water, and large trees make it shady and cool. Because the vast majority of dog owners in this part of town are vigilant about picking up poop, you can set down a picnic blanket without fear of finding an unwelcome surprise smashed on its underside.
